Want to Fix iPhone 5 Battery Drain? (A Workaround)

Question

iPhone 5 (US - AT&T GSM - MD634LL)
iOS 6.0.2 (10A551)
Note: What I will detail/propose below is the implementation of a workaround to make do with what we have until Apple provides the solution.
The hard truth to swallow for loyal Apple customers and device users is that the hardware Apple used in the iPhone 5 is power-hungry, services provided via iOS are not optimized to reduce resource consumption, and if Apple did not also include a bigger battery with the iPhone 5 then owners would be even more upset.
So, long story short...
Over five nights, I did some simple tests.
The first night, I left my phone in Airplane Mode overnight - some drain while idle.
The second night, disabled Spotlight Search indexing and left my phone in Airplane Mode overnight - minimized drain while idle.
The third night, I turned off wifi - small amount of drain and I noticed that my cellar data usage (sent and received) increased by just over a couple of megabytes in total. Strange...
The fourth night, I enabled logging on my router. Since all of my wireless devices are assigned static addresses, I can narrow down data hogs pretty easily and see where they are going to get data and how much data was sent/recevied. With wifi left on, many hundreds of requests were sent to push*.apple.com servers by my iPhone 5 and a couple of megabytes worth of data were sent/received. Why? Because I had push enabled for iCloud (I always set my email accounts to Manual data fetching). It seems to me that push is still not push and that iOS will check to see if updated data in iCloud needs to be fetched. Push in the iOS world is another way of saying "try to fetch data much more frequently than the periodic fetch data settings." I also looked at my OpenDNS stats since I got the iPhone 5 in early December and these servers made up a hugely massive chunk of all my internet traffic at home. It is fair to note that my wifi-only third-generation iPad makes many hundreds of requests to those servers as well, but I am guessing that the hardware used for it is not as power-hungry and I do not have BT enabled and I do not have any battery drain while idle issues with it.
The fifth night, with both push and fetch disabled, all notifications disabled, as many location services as possbile disabled, all cellular data services disabled, Spotlight Search not indexing anything, I left wifi and cellular on and noticed that my battery drained only a couple percent while my iPhone 5 sat idle on my nightstand and only a minimal amount of cellular data was used (for what I do not know...).
So, until/if Apple decides to do something, if you want to maximize your iPhone 5 battery's charge, then I recommend implementing the following:
High Prority Settings
If you do not use it, turn off Spotlight Search completely by deslecting all of the items that it can index. As with newer versions of OS X, services related to Spotlight Search indexing seem to run quite often and for extended durations of time.
Unless you are a doctor or a very important person in another profession that must know when you get a new email, turn Push off and set Fetch to manual for all iCloud and all mail accounts. You can also go one step further and set each account to "Manual".
Unless you connect to a very underutlized 4G LTE network, turn off LTE. I tested this change and the difference between standard 4G and 4G LTE on AT&T network in Denver metro area is negligible.
Turn off ALL iOS System Services for Location Services. They do nothing but track you for your Apple's location-based advertising platform. For most, setting the time zone is done when the phone connects via celluar or wifi, and, my car has a navigation system with traffic data and I use Google Maps if I need navigation or traffic data when not in my car. Not a single Apple iOS System Location Service is absolutely necessary and will drain your battery.
Medium Priority Settings
Disable using cellular data for everything if possible. I still choose to leave it on for "iCloud Documents" and that doesn't seem to hurt things.
Disable Location Services for as many apps as possible/reasonable. Do at least leave "Find My iPhone" enabled. Note that some other apps may require that they be able to use your location (e.g. SiriusXM).
Disable as many Notifications (everything about Notifications - banners, alerts, badges, sounds, etc.) as possible.
Low Priority and Typical Settings
Reduce screen brightness as much as possible. Approximately 33% seems to suffice. Auto brightness can be left on since it seems to never really be used anyway.
Turn off Bluetooth when you do not need it enabled.
Turn off any automatic downloads for iTunes and App Stores, and Podcasts.
So, yep, a total PITA. But by doing all of the above, a full battery charge lasts several days with 10+ (or more) hours of actual usage. I hope this helps anyone else that attempts to do the same. Screenshots for those unfamiliar with the key settings above are included below (everything is done via the Settings - aka Preferences - app with a "gear" logo).
Disable Spotlight Search Indexing
Push and Fetch for iCloud and Mail Accounts
Turning Off LTE
System Location Services
Celluar Data Settings
Notifications
Automatic Downloads (apps, music, iBooks and podcasts) for "iTunes & App Stores" and "Podcasts"

Answer 1

Hello,
I am currently an owner of an Ipod Touch 4th generation.
I have had battery drain problem on the Ipod Touch 4th generation.
But, I found a solution that works for me:
Do the IOS update (the one that is the latest, or if you already did, then proceed to step 2)
Reset All Settings: SETTINGS>GENERAL>RESET>RESET ALL SETTINGS
Use it until it dies (automatically shuts off)
Plug into Charge
Leave it 1.5 hours or longer after it reaches 100% --> Undisturbed (preferably overnight)
Give it a few days to Calibrate
This has helped me on my Ipod Touch 4th generation, running IOS 6.0.1
The battery seems to give me 2 days 30 hours of standby, and 10 hours and 15 minutes of usage.
Thats pretty good!
